SAML custom user details

Hi!

I'm trying to implement a custom user detail service for Spring Security SAML. Can someone give me a kick-start on how to implement this? Where should I hook this up in the security context? What classes do I need to implement and override?

Thanks for all answers :)

Our namespace takes care of this. Take a look at the docs for our spring quickstart app. Then take a look at the source code for our spring extension (which is based on spring saml) to see how we implement it.
